BACKGROUND OF THE INVENTION
This invention relates generally to copy holders, that is, devices to hold printed or handwritten copy for display by the user of a computer keyboard. More particularly, this invention relates to a copy holder for use with a portable notebookcomputer.
BACKGROUND OF THE INVENTION
In the field of computers, notebook computers have become very popular. Notebook computers are used by people while traveling as well as in office or home environments. Notebook computers may be used in cramped quarters such as on airplanes andcommuter trains. Typical copy stands used in an office environment for holding copy for viewing while typing on a computer keyboard are inappropriate for use on a notebook computer, especially in cramped quarters where there may be no room for anexternal copy stand.
Several copy holders have been suggested by the prior art for use on a notebook computers. An important consideration, however, for attachment of a copy holder to a notebook computer is that a notebook computers display is a liquid crystaldisplay screen, which may be easily damaged by the attachment of clamps or other clipping devices, as shown in some of the prior art. Additionally, the prior art notebook computer copy holders are not suitable for supporting relatively heavy copy, suchas note pads and booklets.
The devices shown in the prior art also do not provide support for more than one piece of copy material, for example when a user desires to enter data from two different hard copy sources.
It is, therefore, an object of this invention to provide a means for holding copy for a notebook computer.
Another object of the present invention is to provide such a device which can be attached to a notebook computer screen without damaging the screen.
Another object of the present invention is to provide such a device which can be mounted on the back of a notebook computer screen without adding significant thickness dimension to the combined package.
It is still a further object of the invention to provide such a device which can support copy on either or both sides of a notebook computer screen.
It is yet another object of the present invention to provide such a device which can support relatively heavy copy materials.
It is a further object of the present invention to provide a copyholder for use with a portable notebook computer which copyholder may be detached from said computer to stand alone.
A still further object of the present invention is to provide a notebook computer copyholder which may be articulated to provide privacy screens.
Yet another object of the present invention is to provide a notebook computer copyholder with means for securing the copy to the copyholder.
SUMMARY OF THE INVENTION
The above objects of the invention, and others, are met by a notebook computer copy holder produced from rectangular, relatively stiff sheet elements slidably disposed between upper and lower parallel channels affixed to the back of a computerscreen. Hollow tubular members of square cross section are fixed at the top and bottom edges of the support sheets to slide laterally within the upper and lower channels. It should be recognized that the hollow tubular members may be of any suitablecross sectional shape, and are not intended to be limited to a square cross section.
The device is flat and rectangular in shape when in storage mode and attaches to the back of a laptop or desktop computer. This device is not thick enough to prevent the computer from fitting in its carry case. The device may be attached toservice the left or right or both sides of the computer. It extends out to one or both sides of the monitor screen and supports various media so that referencing the media while using the computer is easy and comfortable. The device may be fabricatedfrom strong but lightweight plastic or metal.
In the preferred embodiment, multiple sheets may be stacked to telescope laterally from the back of the notebook computer screen to adjust the size of the lateral copy holder. Also, two copy holders may be slidably stored on the back of thenotebook computer screen so that either or both may be extended laterally to support copy on either or both sides of the screen.
When extended away from the body of the screen, the lateral copy holder sections can be hinged so that they can be individually folded toward the user for ease of viewing or privacy.
An L-shaped support member is provided, with its horizontal leg stored within the bottom square tube of each side of the copy holder. The vertical leg of the support member is rotatably attached to the edge of the copy holder. When the supportmember is removed from the square tubing and adjusted for position, it can be used to support the copy holder under relatively heavy loads, resting on the horizontal leg of the support. This support member can also be used to support the copy holder ofthe present invention when it is released from the aforementioned channels.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
A notebook computer copy holder incorporating the various features of the present invention is illustrated generally at 10 in the figures.
The copy holder embodying the present invention is comprised primarily of flat panels slidably mounted in upper and lower parallel guide channels which are attached to the upper and lower areas, respectively, of the back of a notebook computerscreen.
The notebook computer copy holder is designed for being removably secured to the screen 12 of a notebook computer for holding documents 14 for viewing while using the computer. Moreover, in the preferred embodiment the copy holder 10 is designedto be usable with a notebook computer on either or both sides of the screen 12. Further, the copy holder 10 is designed such that documents 14 retained thereby are not damaged while being retained.
The back of a notebook computer screen 12 serves as the notebook computer lid when closed and is generally fabricated of plastic or metal such as aluminum or titanium, which is less apt to be damaged by contact with foreign items such as adhesiveor clamps than the display screen itself. For this reason, the present invention is designed to be attached to a notebook computer at the back of the display so as not to damage any of the pixels of the display screen.
As shown in FIG. 2, upper channel guide 16 is horizontally affixed to the top of the back of the computer screen. This affixation can be effected by any suitable permanent or semi-permanent adhesive. It is anticipated that these channels can beattached by double-sided adhesive tape or by various hook-and-loop attachment tapes such as VELCRO.RTM..
Lower channel guide 18 is similarly affixed at the bottom of the back of the notebook computer screen. Upper channel guide 16 is essentially a downward facing U-channel. Lower channel guide 18 is essentially an upper facing U-channel and isparallel to upper guide channel 16. This arrangement provide parallel tracks for the components of the copy holder of the present invention.
In the preferred embodiment, two substantially identical sections A and B of copy holder 10 are slidably mounted in channel guides 16 and 18. Each of the channel guides is somewhat flexible and biased inwardly to pinch panels A and B to somewhatretard their lateral movement.
Panel A is shown in FIGS. 4 and 5 in greater detail. Panel A includes primary sheet 20 and subordinate sheet 22. Primary sheet 20 includes square cross-section tube 24 fixed to the top edge of primary sheet 20 and square cross-section tubes 71affixed to the bottom of primary sheet 20. These tubes extend the width of primary sheet 20. Second upper tube 26 is of substantially identical hollow tube cross-section, and is affixed and stacked on top of the first tube. Second lower tube 72 is ofa substantially hollow tube cross-section and is affixed to and stacked below tube 71. Tubes 26 and 72 extend along the top and bottom edges, respectively, of panel A from the outer top corner 28 past the inner top corner 30, extending the lengthapproximately double the width of primary sheet 20.
Subordinate sheet 22 is slidably mounted in channels 76 and 77 attached below tube 24 and above tube 71. Horizontal ledge flap 36 is provided at the bottom of primary sheet 20. This ledge flap holds the bottom edge of sheets of copy mounted onPanel A of 10 (shown in phantom in FIG. 5). This ledge flap has horizontal interior ridges 38 in order to slightly adjust the distance that the media sits away from the holder and change its angle to reduce glare. A similar and cooperating ledge flapis affixed to the bottom edge of subordinate sheet 22.
Stiff wire retainers 40 are pivotally attached at each corner of panel A. These wires are designed to be used to retain sheets of paper on the copyholder.
Near the top of primary sheet 20 is horizontal retaining band 42. Retaining band 42 is comprised of two elements 44 and 46 which are slidably connected by sliding clasps 48 and 50. Band 42 provides the function of retaining copy, especially thebacking boards of writing pads. Also, the clasps 48 and 50 limit the travel of the bands, and therefore, the separation of primary and secondary plates as they are telescoped apart.
Section B is essentially identical in construction to Section A of copy holder 10, being a mirror image thereof. The difference between the construction of Section A and Section B is that Section B has one square upper support tube and onesquare lower support tube. Each of these support tubes extends from the left upper edge and left lower edge, respectively of Section B, extending past the right edge of Section B so that the total length of each tube is approximately double the width ofSection B. Upper and lower tubes 32 and 34 on Section B are of square cross-section, and of smaller dimension than the square structural tubes on Section A. Upper tube 32 on Section B is aligned with second upper tube 24 on Section A, similarly lowertube 34 on Section B is aligned with upper tube 71 on Section A. Tube 32 and tube 34 are dimensioned to slide into tubes 24 and 71, respectively.
Auxiliary support 60 is L-shaped, including vertical leg 62 and horizontal leg 64. Horizontal leg 64 is stored in the lower tube. Vertical leg 62 is engaged by removable support yoke 66, which is pivotally and slidably mounted to outer verticaledge 73 of section A. In use, auxiliary support 60 is removed from the lower tube and support yoke 66, then re-attached to support yoke 66 and adjusted by sliding vertical leg 62 in support yoke 66 and adjusting the angle of support yoke 66 relative tothe plane of section A. In this manner, auxiliary support 60 may be used to support Section A as shown in FIG. 1. This support is useful if the copy is of significant weight. Additionally, the copyholder of the present invention may be removed from thenotebook computer by completely sliding rails away from the computer. The copyholder can stand on its own by using auxiliary support 60.
The copyholder panel may be used substantially parallel to the alignment of the computer screen. 12 or they may be articulated towards the user for comfortable viewing or to function as "blinders" to provide screen privacy, for example, in anairliner. Hinges 68 and 70 are located on tubes 26 and 72. Hinges 68 and 70 are exposed operational when the panels are extended past the edge of the screen. Hinges 74 and 75 function in the same way for Panel B. Suitable hinge assemblies are providedto enable the entire assembly to pivot about the vertical line between the two hinges so that the assembly may be folded forward. The hinges provided are provided with tight tolerances to enable the apparatus to be semi-rigidly set at various positions.
From the foregoing description, it will be recognized by those skilled in the art that a notebook computer copy holder offering advantages over the prior art has been provided. Specifically, the notebook computer copy holder provides a means forholding a document or group of documents in relation to a notebook computer screen for viewing while typing. The copy holder of the present invention may be closed and stored while attached to the back of the compute screen or removed after use suchthat the notebook computer is not damaged. The copy holder provides a means whereby copy may be held with respect to either side or both sides of the notebook computer screen.
While a preferred embodiment has been shown and described, it will be understood that it is not intended to limit the disclosure, but rather it is intended to cover all modifications and alternate methods falling within the spirit and the scopeof the invention as defined in the appended claims.
